Title: Update regex for Irish banks to include bank identifier.

The regex for Irish banks includes the named group ```branch_identifier``` twice. The first instance should be the ```bank_identifier```.

Also updates gemspec to specify the version of ```activemodel```, as ```ActiveModel::Model``` is not available before version 4.0
